MWR Air Filters are built upon 2 decades of experience in developing and producing high performance air filters for road, race, and off road use.
This experience has been gained working with some of the biggest air filter companies in Europe in areas such as World MX, Dakar (bikes, cars and trucks), Moto GP, WSB, BSB, AMA and even Rallycross. The knowledge gained during this period was invaluable and led MWR to develop their range of performance foam filters.
The HE (High Efficient) air filter for road & race bikes
The revolutionary HE Air filter increases power and reduces intake noise. Unlike any other sports filter all inlets will get the same quantity of air, regardless of the speed of the motorcycle or wind directions. This is because of the unique design of the Air Splitter Plate (see illustration to understand how the Air Splitter works) and how it evenly distributes air throughout the airbox. No different fuel-mappings between internal & external or front & rear cylinders are needed. Clean and re-oil once a year.
Full Race filter (black)
MWR developed the Full Race Filter for riders looking for the best out of their ZX-4RR when participating in trackdays or racing. They offer the best air flow possible from such a small filter.
The MC-040-15-HE has a printed logo on the front of the filter as indication of how dirty the filter is. The filter will be dirty very quickly (just like all other airfilters for this bike) because of the small size of the filter. It is very important to keep this filter cleaned and oiled regularly.
